Be it known til 21b1,HENRY COWVAN, a citizen of the 'United States, and a resident of New'York city, in the county of New York, and State of New'Yoi-k, have invented certain'inew and useful Improve ments f in. coffee Percolators, 'of' which the following is a full, clear, andxexact description.

Among the principal objects which the present invention has in view are: to lock a removable cover for a container of the character mentioned in service position; to

simplify and cheapen the construction; and to avoid unsanitary featuresof construction.

Drawings.

Descrz'p tz'on.

As shown in the drawings the percolator container has a "cylindrical bodyport'ion 8. The body portion 8 is constructed of thin metal. such as aluminumand is provided with perforations such as'are indicated by the numeral 9 throughout its structure. The body portion 8 is reinforced by annular projected ridges 10 and 11 to render thestructure more rigid and less liable to being crushed. purpose of locking in service the'curved bottom 12. Thebottom 12 has an annular ridge13 which is forced over or spun over the ridge 11 as illustrated in Fig. 1 to thereafter maintain permanent the connection between the said bottom 12'and the body por tion 8. The ridge 1O forms'a stop member for the curved top 14, the lower edge wherej of rests on the ridge 10 in service.

The percolator is supported in service by a hand '15, at the upper end whereof is a hook 16 that rests over the upper edge of the coffee pot or other utensil to support the percolator body and the contents therein, above the bottom of said pot or utensil. To permit the use of thin sheet material in the construction of the handle l5,-the same has Specification oflietters Patent.

The ridge 11 serves the further COFEEE-PERCOLATOBL.

-'longitudinal ridge '17 which 'stiifens the construction material. Ahandle, is secured to the body portion in any suitable manner, that shown in the drawings being by use of rlvets 18. w

'percolator 1s. in service, a-projection 19is forced forward 'fromthe front face of the handle 15 to overhang the annular ridge 20; with whichthe-cover 14 is j acent the edge thereof.

As shown best in Fig. 1 of the drawings,

provided adf To look the cover inpo'sition when the the ridge 20 extends under the projection 19 which is thereafter held in service relation to the'ridge 20' by theresiliency ofthe flat portion 21- of the handle situated :be-

tween the said projection 19 and the por- '7 tion of the handle which is rigidly secured to the body portion 8. At the forward side of the body portion 8 and in line with the ridge 20 is a second projection 22 Which is struck out and forward from the annular,

rim of the body portion 8. Sufficient resiliency exists in the structure of the cover 1-1 to yield sufficiently for the lower edge of the same to pass over the projection 22'to relation theret From the foregoing, it-will be seen that after percolator has received its charge of coffee or other material, the cover 14: is

placed in position. This is done by initiallythereafter snap under the same in looking into line when the ridgeQOg-of the cover has enteredbelow the lower end of the projec tion 22. The cover 14 is then pressed down into. positionwhere the ridge 20 likewise engages the projection 22 at the front of the percolator body. It will be seen that in this position force has to be applied to the cover to remove the same from its service relation to the body portion 8. This avoidsthe ac cidental dislodgment of the cover 14, to

which disadvantage the articles of this char- "acter heretofore have been subject.

Claims.

an open-ended container; a suspension memher .llgldly attached thereto; a removable cover for said container, said cover having I 1. An article'as characterized comprising g memes pension member for engaging said ridge when said cover is installed in service.

2. An article as characterized comprising an open-ended container; a suspension member rigidly. attached thereto; a removable cover for said container, said cover having an outwardly projecting reinforcing ridge adjacent the open edge thereof; and a projection formed on said suspension member for engaging said ridge to hold said cover in service relation to said container.

3. An article as characterized comprising an open-ended container; a suspension member rigidly attached thereto; a removable cover for said container, said cover having an outwardly projecting reinforcing ridge adjacent the open edge thereof; a locking member permanently formed on said suspension member for engaging said ridge When said cover is installed in service; and locking means for holding said cover in service, embodying a projection formed on the edge of said container for engaging internally the reinforcing ridge on said cover.

4. An article as characterized comprising an open-ended container; a suspension member rigidly attached thereto; a removable cover for said container, said cover having an outwardly projecting reinforcing ridge adjacent the open edge thereof, and a projection formed on said suspension member for engaging said ridge to hold said cover in service relation to said container; and locking means for holding said cover in service embodying a projection formed on the edge of said container for engaging internally the reinforcing ridge on said cover.
